![]() If you are using Linux and you want your actions to be safe, you need to know and understand these two commands. Having root user privileges can be dangerous, but using sudo instead of su can help you keep your system more secure. Using “sudo,” you can do pretty much the same things you can with “su.” To use it, you just have to add “sudo” in front of all root commands. Once that time expires, you have to enter your password again to regain root privilege. Also, the root privilege in “sudo” is only valid for a finite time. With “sudo,” you continue to use your user account, but with root privilege, whereas in “su,” you are actually logged into the root account. This is different from “su” which is not temporary. Sudo stands for either "substitute user do" or "super user do" and it allows you to temporarily elevate your current user account to have root privileges. The Unix command su, stands for “substitute user,” “super user,” or “switch user,” and allows you to log in as root and do whatever you want with the system. I am going to refer to Ubuntu in this blog. Some types, such as Fedora, Red Hat, and openSuSE enable the root user, while others, such as Ubuntu and Debian, do not. Which one you use will depend on which type of Linux you have. ![]() You can either change over to the super user, also known as the root account, using the “su” command, or you can use the “sudo” command. Remember, the power of the root user is immense, and with great power comes great responsibility.When it comes to working with Linux, there are two ways to run administrative applications. Always double-check your commands before running them as root, and only use root access when necessary.įor more information on using Terminal in Ubuntu, check out the official Ubuntu documentation. However, it’s important to remember that running commands as root should be done with caution, as it can lead to system instability or data loss if used improperly. Running Terminal as root in Ubuntu can be done in several ways, each with its own advantages. The -i option stands for “interactive”, and it starts a new shell with root privileges. This command starts a root shell within the current Terminal session, allowing you to run commands as root without using sudo each time. This can be done using the sudo -i command: The third method to run Terminal as root is by starting a root shell inside Terminal. Method 3: Starting a Root Shell Inside Terminal They allow you to run graphical commands with root privileges. The gksu and gksudo commands are graphical front-ends to sudo and su, respectively. Type gksu gnome-terminal or gksudo gnome-terminal and press Enter.Once you’ve installed gksu, you can use it to run Terminal as root: Type sudo apt install gksu and press Enter.If you’re using Ubuntu 18.04 or later, you’ll need to install the gksu package first: If you’re using an older version of Ubuntu, you can skip to the next step. However, these commands are not installed by default on Ubuntu 18.04 and later versions. Method 2: Using gksu or gksudoĪnother method to run Terminal as root is by using the gksu or gksudo command. The gnome-terminal command opens a new instance of the Terminal. The sudo command stands for “superuser do”, which allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers file. This command opens a new Terminal window with root privileges. Type sudo gnome-terminal and press Enter.The first method to run Terminal as root in Ubuntu is by using the sudo gnome-terminal command. ![]() The root user can access, modify, and delete any file on the system, install and uninstall software, and modify system settings. You can think of the root user as similar to the Administrator account in Windows. In Linux, the root user is the superuser and has the highest level of access to the system.
